Electronic Torque Wrench Calibration System with Inversion Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing torque wrench calibration systems fail to accurately simulate real-world torque application conditions, leading to potential device damage due to excessive force application during calibration, as they typically apply torque in a direction opposite to actual usage and lack effective notification mechanisms for excessive torque.
Innovation Solution
A test and calibration system for electronic torque wrenches that includes a base with a sensing device for receiving the wrench's driving portion, a force imposing device to apply torque similar to actual usage, and a calibrating device with a notification unit displaying light signals to alert users of excessive torque, ensuring safe calibration without returning the device to the factory.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the torque detection assembly rotates to simulate actual force imposing situation, then the torque measurement can be obtained, but the test result cannot present the actual force imposing condition because the rotation direction is opposite to practical usage
Solution Approach 1:
The patent inverts the conventional testing approach by having the electronic torque wrench itself apply torque to the testing device, rather than having the testing device rotate the wrench. This reversal ensures the torque application direction matches actual usage conditions, making test results authentic while maintaining measurement precision
2Device complexity
If the base is positioned far from the control host, then the device structure is simplified, but the testing device lacks notification mechanism for excessive torque which may cause device damage
Solution Approach 1:
The patent incorporates a notification mechanism that provides real-time feedback to operators during torque application. The system monitors torque values and notifies users when excessive torque is detected, preventing device damage while maintaining a relatively simple overall structure
3Ease of operation
If manual calibration operation is performed without notification mechanism, then the calibration process is simple, but the calibrating personnel may accidentally cause excessive force imposing resulting in device damage
Solution Approach 1:
The notification mechanism provides continuous feedback during manual calibration operations, alerting calibrating personnel when torque approaches dangerous levels. This allows operators to maintain simple manual procedures while preventing harmful excessive force application through real-time warnings

AI summary
A test and calibration system of electronic torque wrench includes a base, a sensing device, a force imposing device, and a calibrating device. The sensing device is disposed on the first end of the base and includes a receiving socket to receive the driving portion of the wrench. The force imposing device is disposed on the second end of the base for holding the handle portion of the wrench, such that the wrench imposes the torque on the sensing device which measures the actual torque value. The calibrating device is signally connected with the sensing device and the wrench. When a predetermined torque value is different from the actual torque value, the calibrating device generates a calibrating signal to the electronic torque wrench for the calibration operation. Also, the calibrating device includes a displaying unit for displaying the actual torque value.
